  4. Description • Potassium is a: • Light – soft • Silvery - white color • It reacts violently in water

  5. About Potassium • Potassium is not found in free nature. • It was the first metal isolated by electrolysis • Potassium (Potash) is mined in Germany, Utah, California, and New Mexico • It is an alkali metal

  6. About Potassium • Do we need potassium? We need Potassium for our body, Potassium is responsible for our heart beating and the movement of our muscle. It is for fluid balance in our body.

  7. About Potassium • The minimum amount of potassium we should consume per day is 2000 mg • This can easily be obtained by eating vegetables and fruits • Do not consume Potassium from salt such as Potassium Chloride, it can be dangerous for our life • These are some food with high amounts of potassium: • Bananas • Milk • Avocados • Oranges • Fish • Dry Beans • Peanut Butter • Cantaloupe • Mushrooms • Spinach • Potatoes • Watermelon http://startupblog.files.wordpress.com/2009/04/banana1.jpg
